ELEVYATO R.

SPECIFICATION forming part of Letters Patent No. 721,571, dated February24, 1903.

Application filed April 3, 1901.

To all whom, it may concern;

Be it known that I, GEORGE W. KRAMER, a citizen of the UnitedStates,residing at Peoria, in the county of Peoria and State ofIllinois, have invented certain; new and useful Improvements inElevators; and I do hereby declare that the following is a full, clear,and exact description of the invention, which willenable others skilledin the art to which it appertains to make and use the same.

This invention has reference to elevators or conveyers, and. relatesmore particularly to an extensible telescoping conveyer adapted for usein feeding corn to corn-shellers.

The object which I have in view is the profeeder the conveyer of whichis constructed actuated in said elevator or feeder as to adapt itself tothe extensibility of the section of the feeder; and the inventionfurther consists in the detail construction and arrangement of partshereinafter more fully pointed out-in the specification and claimed inthe appended claims, due reference being had to the accompanyingdrawings, forming a part of this specification, in which Figure 1 isaplan View of my improved elevator or feeder. Fig. 2 is a longitudinalsection of the same, Fig. 3 is a cross-section on the line X X ofFig. 1. Fig. 4 is a cross-section on the line Y Y of Fig. 1. Fig. 5 is across-section on the line Z Z of Fig. 1.

In constructing a telescopic extensible conveyer or feeder, such as Ishall hereinafter describe more fully in detail, I have aimed toovercome one or more serious objections and difficulties which are everpresent in belt conveyors, and especially in those which are extensible.

1 and 2 refer to sections of my conveyer or feeder which are arranged tobe extended or telescoped. Section 1 has side framepieces 3, withbeveled or deflected upper portions 5, and-in like manner the section 2has the side frame-pieces 4 and the beveled or deflected upper portions6, and the sections 1 and 2 are dovetailed into each other, as shown at7, and the loweredges of the section 2 slide in and out on cleats 8 ofsection 1, said cleats forming a part of or attached to the sides 3, as

Serial No. 54,171. (No model shown. The section 1 is provided with thelongitudinally-arranged partition or bottom 9,10- cated about central ofthe section, and extends from the inner end to a point removed from theouter end, and the outer end has the partially-inclosed bottom and endportion 10, and 11 is a small roller journaled in the sid es of thesection 1, at the inner end of the same, contiguous to the lower edgesof the sides 3. 12 is'a similar roller, but much larger in diameter,journaled in the sides 3 at the forward end thereof, carried on thespindle which supports said roller, and arranged to impart power theretois a sprocket-wheel 12, located on the outside of the section, as shown,and actuated by sprocket-chain connecti-ouwith the sprocket c of thedrag O. The section 2 has the open inner end and partially-closed bottomand outer end 13, as shown. The sides 2 are arranged with slots 14:,extending from the inner ends to a suitable point near their outer ends,and in these slots or open ways is arranged to slide the partition orbottom 9 of the section 1. 15 is "a partition arranged longitudinally inthe section 2, of suitable length and in such a position that when thesections are telescoped into each other the partition 15 will lie aboveand adjacent to the upper face of the partition 9, the inner end taperedsubstantially as at 16, which will cause the inner end thereof to bearagainst the upper face of the partition 9. 17 is a longitudinalpartition located in the section 2 and beneath the partition 15 and ofsuitable length, and the arrangement is such that when the sections aretelescoped into each other it'will lie below the partition provision ofthe rollers, such as I have described, enables me to provide a conveyerfor said feeder which may be extended to accommodate itself to theextension of the sections or to the telescoping of the same withinthemselves, and this, with an endless belt, having a smoothcarrying-face without having to add to or take away from the same anysections or parts to allow it to accommodate itself to the extension ortelescoping of the sections.

The conveyor consists of the belt 20, which is passed around the roller19 and along over the top of the partitions 15 and 9 to the delivery endof the elevator and thence around the roller 12 and forward to theroller 11 and around said roller and bringing it toward the roller 12,is passed around the roller 18 and along over the top of the lowerpartition 17, and is joined or coupled in any suitable manner to itsmatching end, which was described as passing around the roller 19. Thisarrangement is clearly seen and also understood from an examination ofFig. 2. Thus it will be seen that the roller 18 acts as an idler aroundwhich the belt 20 is carried and keeps the same taut, as by extendingthe section 2 the roller 18 moves toward the forward end of the section1 and will permitthe carrying-face on the upper face of the partitions15 and 9 to be extended, and likewise when the sections are beingtelescoped into each other the movement of the roller 18 toward thedelivery end will take up the slack inci- (lent to such telescoping, andthe carrier remains taut.

I have made provision in this device when used for conveying corn to acorn-sheller to take care of any grain of corn shelled from the cobs asthey are passed to the drag to permit the same from cutting and wearingout the under surface of the belt, which would be the case if theshelled corn were dragged and allowed to pass between the roller 12 andthe belt. It is very easy for loose grains of corn to become lodgedbetween the belt and the partitions 9 and 15, and if there were noprovisions for carrying off this loose grain the same would be draggedalong upon the upper face of the partitions described and passed overthe roller 12, which would in a short time out and wear away the belt,and to take care of this loose grain I have provided in the length ofthe section 1 and contiguous to the roller 12 the chutes 21 and 22,extending from the center of the partition 9 in a slanting direction andhaye the open ways 22 in the sides 3 communicating with said chutes, and23 are guides lying on the face of the partition 9, having the beveledinnerends 24. This arrangement insures that when the grain is beingdragged along the surface of the partition 9 the guideways 24 willdirect the same into the chutes and they together will form asubstantial V, which will cause the grain to be dropped out through theopen ways 22 in the sides 3.

Another advantage which my feeder has is that, providing a conveyer onwhich I use no attachment or slats, I can run the same Very fast, whichwill insure a steady feed of material to the sheller, and one of thedifficult things which I overcome is the necessity of having to stopfeeding a slow conveyer when the mouth of the machine becomes crowded,as it is well known in the use of slow conveyer or feeder where they useslats, the mouth of the machine will become clogged and having to stopfeeding the feeder there will be a period when there will be no materialin the machine; but in a conveyer or feeder of the character described Ican run at an increased speed, and if it so chances that the feed of theelevator or feeder is greater than the capacity of the machine thematerial in the elevator can remain almost at a standstill, as the beltcan slip beneath the material and continue to be run, and when themachine being fed has caught up with the supply there will be no timewhen there is a lack of supply, because as soon as the mouth of themachine is freed the material in the elevator will be fed thereto.

I do not wish to confine myself to the detailed construction andarrangement of parts as illustrated, as it is obvious that variouschanges may be made in the material used, the general design, anddetails resorted to, all of which will come within the scope andprinciple of the invention herein.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent of the United States, is
